First Bio-Based Composite Movable Bicycle Bridge
The first bio-based composite movable bridge has been built in Ritsumasyl, The Netherlands (Fig. 1). This paper describes the material research conducted, and takes a further look at the design of the bridge and its monitoring system. The entire bridge has an overall length of 66 m. The first half is fixed and the second consists of an asymmetrical movable swing part with a free main span of 22 m and a counterweight section of 12 m. The bridge deck is made of 85% bio-based material. In collaboration with universities, research institutes and suppliers, tests and the design of components and materials are performed. The tests are carried out in accordance with guidelines and standards, whereby the outcome is analysed and used as input parameters for the design. Due to a tight schedule for the construction of the bridge, the tests have not been scientifically analysed in detail. The project team succeeded in building a bridge from Bcomp® flax fibres, balsa and a bio-based Epoxy resin—1800 ECO + 1804 ECO made by Resoltech—which serves as an example for building the first green bridge—“green” in the sense that no synthetic chemicals and only natural fibres are used, a completely circular alternative material as one of the many possible alternative answers to tackling climate change. The bridge is equipped with an advanced monitoring system that has been built into the design. The monitoring system collects data on the behaviour of the bio-based deck for most circumstances, such as deformations, moisture content, loads and temperature. The bridge is equipped with optical fibres, with a total of 184 Fibre Bragg Grating (FBG) sensors, installed by Com&Sens.
